‘In doses used as a food supplement, CBD poses few risks, and side effects are unusual but can include a dry mouth or drowsiness,’ reveals Dr Brewer. ‘Higher doses used medically are well tolerated, and there are no serious safety concerns. A World Health Organization report issued in 2017 concluded that cannabidiol does not appear to have abuse potential or cause harm.'
Unfortunately, you don’t. Even though more than half of all U.S. states now allow marijuana for medicinal purposes—and nine of those, plus Washington DC, allow it for recreational use—the Drug Enforcement Agency still views CBD as a banned substance and therefore doesn’t regulate it (since, in the eyes of the law, CBD shouldn’t be on the market). “I can start a company, put oil in a jar and sell it as CBD oil,” says McLaughlin—and no one has to vouch that what’s in there is for real. You have only the manufacturers word for it.
Tetrahydrocannabinol is the most abundant cannabinoid in most medical and recreational marijuana strains. However, in hemp THC is a minor constituent and appears only in trace amounts under 0.3% by dry weight, as required by the U.S. government for hemp products. THC mimics the action of anandamide, a neurotransmitter naturally produced in the human body, and binds to CB1 receptors in the endocannabinoid system found mostly in the brain. The extremely low levels of THC in hemp make hemp oil non-psychoactive and safe for all ages to use.
So Herrera, who's experienced her own share of pain due to a shoulder injury followed by a bout of Lyme disease, went to a local herb shop and bought a vial of the oil, which, by some definitions, is legal in all states if it doesn't contain more than 0.3 percent THC – the psychoactive component of cannabis. She began putting seven to nine drops under her tongue first thing most mornings – and was startled by the results. "It's changed my pain level, my anxiety level and my stress level," says Herrera, who already practiced yoga, meditated regularly, ate a healthy diet and tried conventional medical treatments for pain and mobility. "It was shocking," she says, because she thought her patients' reports were due to the placebo effect. "Right now," she adds, "I feel pretty amazing."
Considered the most scientific method this is also among the cleanest techniques of extraction. Referred to as sub-critical or super critical CO² method, it uses carbon dioxide under different pressures to extract the medicinal oil. This is among the most expensive techniques of extraction due to use of hi-tech equipment that can be operated by trained personnel only. The advantage of this technique is that the end product is the purest form of CBD oil which is highly potent and free of chlorophyll. However if the heat used during extraction is too high it can damage terpenes in the oil that have therapeutic benefits and provide flavor and essence to the oil strain.
The CBD oil derived from cannabis plant is ideal for treating children and adults with epileptic/seizure disorders. This is because of low content of THC which is the main compound responsible for giving pot smokers a high when they take marijuana. In view of the curative powers of CBD oil several states within United States are legalizing its possession among people that are not related to its research. CBD rich oil is also used as a chief ingredient in vaping oil for use in e-cigarettes which can gradually reduce smoking as it does not have the ill effects of regular nicotine rich tobacco smoke that destroys lungs over a period of time.
First, ethanol is a polar solvent. This means that it will readily mix with water and dissolve water-soluble molecules. This creates a great challenge for companies using the ethanol extraction method because chlorophyll is one of the compounds that will easily co-extract. Chlorophyll in the concentrate will result in a dark green coloring and an unpleasant bitter, grassy flavor.
Lisa Hamilton, a jeweler and doula in Brooklyn, NY, knows about the side effects. She recently tried CBD for the shoulder pain that plagued her five years after an accident. Her doctor certified that she was in chronic pain, which under New York State law allowed her to buy from a state dispensary. One Friday, she swallowed two 10-mg capsules, the amount recommended at the dispensary, then took another two on Saturday. “By Sunday, it felt like I’d gotten hit by a truck. Every muscle and joint ached,” Hamilton says. She cut back to one pill a day the following week, but still felt hungover. She stopped after that.
Along with its better-known counterpart, THC (delta-9-tetrahydrocannabinol, the chemical that produces the marijuana high), CBD is one of more than 400 compounds found in the oils of cannabis plant species, which include marijuana and hemp. Unlike THC, CBD will not make you high. That said, this doesn’t mean CBD is not at all psychoactive, as many assert, says Jahan Marcu, Ph.D., director of experimental pharmacology and behavior at the International Research Center on Cannabis and Mental Health in New York City: “CBD does change cognition. It affects mood, which is why people take it for anxiety. And some find that it makes them more alert.”
Anyway, the research showed that in mice, CBD was much more effective when used along with other compounds of the cannabis plant, than when it was used by itself. While they haven’t yet figured out why exactly this is the case, it’s now generally accepted that full-spectrum CBD oil is more effective at treating the majority of medical conditions, than is CBD isolate.
Answering the question “what is CBD oil” would be incomplete without mentioning the many CBD oil benefits. In addition to positively affecting the endocannabinoid system, CBD has been the focus of more than 23,000 published studies about cannabinoids in relation to various medical indications including anxiety, epilepsy, inflammation, cancer and chronic pain to name few. You can even find CBD for pets that is specially formulated to safely allow your pets to experience the natural benefits of CBD.
